+Subject: [PATCH] slirp: use correct size while emulating IRC commands
+
+While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
+'m->m_size' to write DCC commands via snprintf(3). This may
+lead to OOB write access, because 'bptr' points somewhere in
+the middle of 'mbuf' buffer, not at the start. Use M_FREEROOM(m)
+size to avoid OOB access.

+From 80bc935eaaf93e5b9a4efe97abd7c51d645f2612 Mon Sep 17 00:00:00 2001
+From: Thomas Huth <thuth@redhat.com>
+Date: Mon, 16 Dec 2019 14:29:41 +0100
+Subject: [PATCH] qemu-doc: Remove the unused "Guest Agent" node
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The node has been removed from the texi file some months ago, so we
+should remove it from the menu section, too.
+
+Fixes: 27a296fce982 ("qemu-ga: Convert invocation documentation to rST")

+Unicode bidi algorithm.  Arabic and Indic scripts handling (in
+progress).
+
+@item WYSIWYG HTML/XML/CSS2 mode graphical editing.  Also supports
+Lynx like rendering on VT100 terminals.
+
+@item WYSIWYG DocBook mode based on XML/CSS2 renderer.
+
+@item C mode: coloring with immediate update.  Emacs like auto-indent.
+
+@item Shell mode: colorized VT100 emulation so that your shell work
+exactly as you expect.  Compile mode with next/prev error.
+
+@item Input methods for most languages, including Chinese (input
+methods come from the Yudit editor).
+
+@item Hexadecimal editing mode with insertion and block commands.
+Unicode hexa editing is also supported.

+@item Works on any VT100 terminals without termcap.  UTF8 VT100
+support included with double width glyphs.
